C4 needs to always kill tanks with 3! Change ASAP please!

Just snuck up on a totally oblivious tank player at C on Mirak Valley with C4, stuck 3, and detonated. Instead of being rewarded, I basically killed myself because the tank survived (due to Reactive Armor), and I had nothing else I could do to destroy it, so I died. Why am I punished for successfully sticking 3 C4 on a tank?

Tank players SHOULD be punished for being completely asleep at the wheel. The counterplay is they open their eyes and pay attention. This also completely obliterates the classic battlefield strategy of C4 jeeps, one that was never overpowered, but is embedded in the community's DNA. I have so many fond memories of both doing C4 jeep runs in BF3/4, and panicking and shooting at them as someone drives straight towards me while I'm in a tank. Why are we removing this core part of Battlefield's vehicle/infantry balance? 

If you REALLY want them to live 3 with Reactive Armor, give Recon 4 sticks of C4 so they can still kill it, it will just take a little longer. There's no reason for this of course, 3 C4 killing a tank has been balanced in like 5 other Battlefield titles, but at least this would allow Recon to not literally do nothing with C4. 

Never once, in any prior Battlefield title, have I felt that dying to C4 was unfair. Every time it was "whoops I should've payed more attention" or "yeah that was hectic so they totally snuck up on me". 

Absolutely bizarre change. PLEASE change this immediately.
